Continuous casting has been widely applied in the steel industry. As the last step of steelmaking, continuous casting plays an important role in controlling the quality of steel. Argon gas is usually injected to prevent nozzle clogging, encourage mixing molten steel and remove inclusions in the process of steel continue casting.1) The bubble size distribution plays an important role in the gas-liquid flow process. Large bubbles tend to float up to liquid steel surface and may cause the exposed eye of steel around the SEN,2) resulting in slag entrapment at the same time. Small bubbles can be carried to the sidewall and may be captured by solidifying shell, causing defects in the final products, such as pencil pipe, sliver and so on. The operation conditions play a vital role in production efficiency and product quality. Besides, in the turbulent gas-liquid system, the behavior of bubble coalescence and break-up determine the bubble size distribution. Therefore, the research about the Numerical Analysis of Effect of Operation Conditions on Bubble Distribution in Steel Continuous Casting Mold with Advanced Bubble Break-up and Coalescence Models
